Description

CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation of U.S. application Ser. No. 17/116,500 filed Dec. 9, 2020, which claims priority to European Patent Application No. 20382382.8, filed May 8, 2020, the contents of which are incorporated by reference herein in their entirety.
BACKGROUND
The present disclosure relates to a component for use in an alarm system, and particularly to a technique for detecting events when the component is unpowered.
An alarm system, such as a fire alarm system or an intrusion alarm system, comprises a variety of components working in unison to detect and warn people in the event that a change in an environmental parameter has occurred.
If any one of the components of the alarm system, upon installation in the alarm system, is faulty or has been damaged, this can seriously reduce the sensitivity and effectiveness of the alarm system, and thereby its safety.
Testing each individual component or indeed the entire alarm system each time a new component is installed is very time consuming, and in some instances impractical.
A need therefore exists for an improved alarm system component.

The described component may advantageously determine if there has been an occurrence of a predetermined event and store an indication of the occurrence of the event despite power not being supplied to the component. The power source of the monitoring module provides the monitoring module with sufficient power to monitor the status of the component during this period and identify if the component has been manipulated or damaged. A user may check the status of the component and determine if the component is safe to use in an alarm system.
The predetermined event may comprise exposure of the component to a temperature exceeding a predetermined threshold temperature.

The component controller may be configured to begin to initialise upon connection to a power source during installation of the component in an alarm system. Initialisation of the component controller may comprise the subsequent activation and start-up procedure of the component controller.
The monitoring module may be configured to communicate with the component controller via a digital interface.
The component controller may be configured to take an action in response to receiving the stored indication of the occurrence of the predetermined event from the monitoring module. The action may comprise triggering an alert. The action may comprise notifying a user of the occurrence of the event.

The monitoring module may be configured to store the indication of the occurrence of an event in a dedicated field in the memory, wherein the dedicated field corresponds to the particular sensor triggered by the occurrence of a predetermined event. This advantageously allows the component controller to identify which particular predetermined event occurred by the location of the indication in the memory, such that knowledge about the transport or storage conditions of a component can be quickly obtained.
The alarm system may be a fire alarm system.
The component may be a fire detection component, such as a heat detector or a smoke detector.
The component may be a fire alarm control panel, preferably an addressable fire alarm control panel. The component may be a fire suppression component such as a sprinkler system or fire door holder.

 DETAILED DESCRIPTION
FIG. 1 shows a first smoke detector 1, for use in a fire alarm system.
The smoke detector 1 comprises a smoke detector controller 2. The smoke detector controller 2 could be any microcontroller or processor suitable for controlling the smoke detector 1 during normal operation, i.e. after the smoke detector 1 has been initialised in the fire alarm system.
The smoke detector controller 2 is configured to operate the smoke detector 1 during normal operation, for example, detecting an increase in smoke levels, determining that the smoke levels exceed a predetermined threshold value, and communicating to a fire alarm control panel via a network that the smoke levels have exceeded the threshold value.
The smoke detector 1 also comprises a monitoring module 4. The monitoring module 4 comprises a RFID tag and an antenna 14 for receiving and transmitting wireless signals.
The RFID tag is a semi-passive RFID tag and comprises a local source of power, such as an internal battery 6. The internal battery 6 provides the RFID tag with power so that it may function when the smoke detector 1 (and the smoke detector controller 2) is not being supplied with power through connection to a power source, such as the power source of the fire alarm system, e.g. a mains power source.
The monitoring module 4 is configured to determine occurrence of a predetermined event 12 and to store an indication of the occurrence of the event.
In this embodiment, the monitoring module 4 is configured to determine if the smoke detector 1 has been exposed to a temperature above a predetermined temperature threshold. Exposure to high temperatures may internally damage the smoke detector 1 and modify its sensitivity, thus rendering it unsafe.
The monitoring module 4 comprises a heat sensor 8. The heat sensor is powered by the internal battery 6. The heat sensor 8 is configured to detect an ambient temperature within the proximity of the smoke detector 1. The monitoring module 4 is configured to periodically interrogate the heat sensor 8 to determine whether the smoke detector 1 is being exposed to a temperature above a predetermined temperature threshold.
The monitoring module 4 further comprises a memory 10. Responsive to determining that the smoke detector 1 has been exposed to a temperature exceeding the predetermined threshold, the monitoring module 4 will store a flag within the memory 10 as an indication of the occurrence of this event. Optionally, the monitoring module 4 may record additional information, such as a maximum temperature to which the smoke detector 1 was exposed.
As discussed above, the monitoring module 4 comprises an RFID tag. The RFID tag allows an external RFID reader device to interrogate the monitoring module 4 to determine whether a flag has been stored in the memory 10 of the monitoring module 4 to indicate that the smoke detector 1 has been exposed to a temperature exceeding the predetermined temperature.
Additionally, or alternatively, the smoke detector controller 2 may be configured to internally communicate with the monitoring module 4 through a digital interface 16. For example, the smoke detector controller 2 may be capable of interrogating the monitoring module 4 to determine whether a flag has been stored in the memory 10 of the monitoring module 4 to indicate that the smoke detector 1 has been exposed to a temperature exceeding the predetermined temperature.
A method of monitoring the smoke detector 1, while the smoke detector 1 is not being supplied with power, is now described.
When the smoke detector 1 is in a state where it is not being supplied with power (e.g. the smoke detector 1 is stored in a warehouse or is being transported), the smoke detector 1 may experience a predetermined event 12 such as exposure to a temperature above a predetermined threshold.
Exposure to a temperature above the predetermined threshold will trigger the heat sensor 8. The monitoring module 4 determines that the smoke detector 1 has been exposed to excessive temperature, and in response stores an indication of the occurrence of the event in the memory 10 of the monitoring module 4.
The smoke detector 1 is therefore able to monitor the status of the smoke detector 1 during a period when it is not being supplied with power, and determine if the smoke detector 1 has been exposed to an excessive temperature that may have a negative impact on the normal mode of operation of the smoke detector 1.
In the illustrated embodiments, the monitoring module 4 can be interrogated in two ways.
In a first instance, the monitoring module 4 may receive a RFID read request from a transceiver (interrogator) via the antenna 14 of the RFID tag. In response to the RFID read request, the monitoring module 4 is configured to transmit any stored indications to the transceiver. In this way a manufacturer can advantageously check, before delivery to an end user, if a smoke detector 1 has been exposed to an excessive temperature during a period of storage. The use of an RFID interrogator, which does not require line-of-sight in order to interact with RFID tags like monitoring module 4, means that with a sufficiently powerful excitation field multiple smoke detectors 1 may be checked simultaneously, which can increase the speed and efficiency of the quality control procedure. Similarly, a transceiver may be utilised by the end user to check if the smoke detector 1 has been exposed to excessive temperature prior to receipt by the end user.
In a second instance, upon commencing initialisation of the smoke detector 1 (e.g. when the smoke detector 1 is connected into an alarm system during installation and is supplied with power), the smoke detector controller 2 starts up and transmits a read request to the monitoring module 4 to see if an indication of the smoke detector 1 being exposed to excessive temperature has been stored. If such an indication is returned as a result of the read request, then the smoke detector controller 2 may notify a user (which may be a maintenance engineer, or the like, tasked with installing the smoke detector 1 in the fire alarm system) that the smoke detector 1 has been exposed to excessive temperature and may be internally damaged as a result. The smoke detector controller 2 notifies the user by activating a notification means (not shown) of the smoke detector 1, such as an LED or buzzer.
FIG. 2 shows a second smoke detector 101 for use in a fire alarm system.
The second smoke detector 101 operates in a similar manner to the first smoke detector 1 described above, but differs in the following aspects. Like elements are numbered with corresponding reference signs, but incremented by 100.
In this embodiment, the monitoring module 104 is configured to determine if the smoke detector 101 has been manipulated in a particular manner, and thus comprises a manipulation detection switch 108. Unauthorised manipulation of the smoke detector 101 may cause internal damage and the smoke detector 101 could become faulty and not suitable for installation in the fire alarm system.
The manipulation switch 108 is an embedded mechanical switch, which in this embodiment connects the monitoring module 104 to the internal battery 106. When the smoke detector 101 is manipulated in a particular manner, such as when the housing of the smoke detector 101 is removed, the switch 108 connects the monitoring module 104 to the internal battery 106, which is normally disconnected from the monitoring module 104 in this embodiment. Therefore, upon supply of power from internal battery 106, the monitoring module 104 detects that the smoke detector 101 has been manipulated and the monitoring module 104 will store a flag within the memory 110 as an indication of the occurrence of this event.
A method of monitoring the second smoke detector 101, while the smoke detector 101 is not being supplied with power, is now described.
When the smoke detector 101 is in a state where it is not being supplied with power (e.g. the smoke detector 101 is stored in a warehouse or is being transported), the smoke detector 101 may experience a predetermined event 112 such as unauthorised tampering with the smoke detector 101.
The unauthorised tampering, particularly the removal of the housing of the smoke detector 101, will cause the switch 108 to connect the monitoring module 4 to the internal battery 106. The monitoring module 104 detects that power from the battery 106 has been supplied and therefore determines that the housing has been removed. In response, the monitoring module 104 stores an indication of the occurrence of manipulation in the memory 110 of the monitoring module 104.
As above, the monitoring module 104 may be interrogated by the smoke detector controller 102 or by an RFID interrogator.
Whilst two exemplary events are illustrated above, being exposed to excessive temperature or manipulation of the housing, it will be appreciate that other types of events may be detected by similar techniques. For example, shock damage may be detected by a suitable shock sensor, for example including an accelerometer.
Furthermore, the detection techniques used in either of the first and second smoke detectors 1, 101 may be used for detection of the other predetermined event. For example, a mechanical switch could be provided for connecting the battery 6 to the monitoring module 4 when the temperature exceeds a predetermined temperature. Likewise, an active sensor could be provided for detecting that the housing of the smoke detector 101 has been removed.
In a further alternative embodiment a monitoring module 4 may comprise both a sensor 8 for detecting excessive temperature and a sensor 108 for detecting tampering. Then, the monitoring module 4 may store the indication of the occurrence of either predetermined event 12, 112. This advantageously allows the controller 2 or transceiver to quickly identify which particular predetermined event 12, 112 occurred, such that knowledge about the transport or storage conditions of the smoke detector 1 can be obtained.
Whilst the technique above has been described within the context of a smoke detector, it may be similarly employed in other components used within an alarm system.
